From: Ben Warren <b...@skyportsystems.com> This patch set adds support for passing a GUID to Windows guests. It is a re-implementation of previous patch sets written by Igor Mammedov et al, but this time passing the GUID data as a fw_cfg blob.
This patch set has dependencies on new guest functionality, in particular the support for a new linker-loader command and the ability to write back data to QEMU over a DMA link. Work is in flight in both SeaBIOS and OVMF to support this. The SeaBIOS project is awaiting committing of this patch set before pulling in the matching patches: https://www.seabios.org/pipermail/seabios/2017-January/011097.html v4->v3: - Rebased to top of tree. - Re-added document patch that was accidentally dropped from the last revision. - Added VMState functionality so that VGIA is restored properly. - Added Unit tests v2->v3: - Added second writeable fw_cfg for storing the VM Generaiton ID address. This uses a new linker-loader command for instructing the guest to write back the allocated address. A patch for SeaBIOS has been submitted (https://www.seabios.org/pipermail/seabios/2017-January/011079.html) and the resulting binary will need to be pulled into QEMU once accepted. - Setting VM Generation ID by command line or qmp/hmp now accepts an "auto" value, whereby QEMU generates a random GUID. - Incorporated review comments from v2 mainly around code styling and AML syntax - Changed to use the E05 ACPI event instead of E00 v1->v2: - Removed "changed" boolean parameter as it is unneeded - Added ACPI Notify logic - Style changes to pass checkpatch.pl - Added support for dynamic sysbus to pc_piix boards Ben Warren (7): ACPI: Add a function for building named qword entries linker-loader: Add new 'allocate and return address' cmd docs: VM Generation ID device description ACPI: Add Virtual Machine Generation ID support PC: Support dynamic sysbus on pc_i440fx tests: Move reusable ACPI macros into a new header file tests: Add unit tests for the VM Generation ID feature Igor Mammedov (2): qmp/hmp: add query-vm-generation-id and 'info vm-generation-id' commands qmp/hmp: add set-vm-generation-id commands default-configs/i386-softmmu.mak | 1 + default-configs/x86_64-softmmu.mak | 1 + docs/specs/vmgenid.txt | 40 ++++++ hmp-commands-info.hx | 13 ++ hmp-commands.hx | 13 ++ hmp.c | 21 +++ hmp.h | 2 + hw/acpi/Makefile.objs | 1 + hw/acpi/aml-build.c | 28 ++++ hw/acpi/bios-linker-loader.c | 71 +++++++++- hw/acpi/vmgenid.c | 244 +++++++++++++++++++++++++++++++++++ hw/i386/acpi-build.c | 9 ++ hw/i386/pc_piix.c | 1 + include/hw/acpi/acpi_dev_interface.h | 1 + include/hw/acpi/aml-build.h | 4 + include/hw/acpi/bios-linker-loader.h | 7 + include/hw/acpi/vmgenid.h | 32 +++++ qapi-schema.json | 31 +++++ stubs/Makefile.objs | 1 + stubs/vmgenid.c | 14 ++ tests/Makefile.include | 2 + tests/acpi-utils.h | 75 +++++++++++ tests/bios-tables-test.c | 72 +---------- tests/vmgenid-test.c | 184 ++++++++++++++++++++++++++ 24 files changed, 794 insertions(+), 74 deletions(-) create mode 100644 docs/specs/vmgenid.txt create mode 100644 hw/acpi/vmgenid.c create mode 100644 include/hw/acpi/vmgenid.h create mode 100644 stubs/vmgenid.c create mode 100644 tests/acpi-utils.h create mode 100644 tests/vmgenid-test.c -- 2.7.4
